As tragic a story as this is, i could help put piss myself laughing while watching that clip.
Firstly, seems as i don't agree with keeping animals in such conditions and for the purpose of performing, so pretty pleased man came unstuck there.
And secondly, if you listen to the soundtrack you can actually hear some guy singing (37 secs in) "NA NA-NA NA-NA NA!" while other around hime oare obviously shitting themselves and running for their lives.
Call me sick but it made me laugh
